TECMATE OptiMate Lithium LFP 4s 0.8A Quad Bank — 12.8V 0.8A, 4 charging banks

OptiMate Lithium 4s quad bank is a sealed, multi-step charger and maintainer designed for LiFePO4 batteries. ⚡️ It brings batteries safely to full charge and then keeps them at optimal health without supervision.

All four charge banks are electrically isolated and operate independently, so you can service batteries separately or while they remain connected in series. The unit reactivates batteries from sleep or deep-discharge protection and performs state-of-health tests to warn of battery damage.

Built for continuous use, it offers full electronic protection, weather resistance to IP54, and energy-saving standby power for efficient 24/7 maintenance.
